Gobar was the last king installed by Debera before both were removed and executed by the Saraighatia Ahom officers under the leadership of Atan Burhagohain.
[1][2] After the deposition and execution of Udayaditya Singha in 1672, the Ahom kingdom entered into a period of weak kings, with de facto power wielded, successively, by three prominent ministers: Debera Barbarua, Atan Burhgohain, and Laluk Sola Borphukan.
By a series of cold-blooded murders Debera purged the capital of his opponents and rivals, though most of the powerful Ahom nobles were stationed at Guwahati.
Debera also planned to kill Lao Deka, the younger brother of Laluk Sola Borphukan, but his execution was postponed to an appropriate occasion in future.
[3] In order to secure his position for the future, Debera Borbarua planned to get rid of Atan Burhagohain and Laluk Sola Borphukan.
Two agents of Debera---Betmela and Lao Deka of Dihingia Khatowal Chetia family---were dispatched to Guwahati to bring Laluk Sola Borphukan to Garhgaon.
Khamat Pachani, the son of the Burhagohain arrived at Guwahati the next day and warned his father not to follow the royal orders as they were actually from Debera Borbarua.
Atan Burhagohain along with Laluk Sola Borphukan held consultations with the Phukans, the Rajkhowas and the Hazarikas stationed at Guwahati to discuss their future course of action.
They placed before them articles sacred to the Vaishnavas,- the manuscripts of Gita, Bhagavat and Ratnavali; Salagram, copper, and the tulasi or basil plant; and in the presence of the Brahmans they took the following oath,-“If we act contrary to the plans and orders of Your Excellency all the merits which we have earned hitherto will be nullified, our ancestors will be doomed to perdition and go to hell.
Having heard of the approach of the Guwahati army he left his residence in battle-array solemnizing the occasion by beheading Lao Deka, brother of Laluk Sola Borphukan, at the principal entrance of the capital city of Garhgaon.
Even though Gobar’s reign was very short, he will be remembered as the first king from the famous Tungkhungia branch of Royal Ahom dynasty, as his son Gadadhar Singha firmly established the power of the monarch in 1681 putting an end to the period of ministerial supremacy.
